10 Claims.

The present invention relates to improvements in sash and store front constructions.

Generally speaking, this invention has to do with an improved type of construction for supporting and holding lights of glass in glazed openings, for example, in windows, store fronts, and the like. The usual type of sash and store front constructionordinarily comprises a stationary back section and a movable front section associated with one another in a manner to clamp the light of glass in place therebetween. The back section is usually supported on a wooden sill and secured to a wooden back stop carried by said sill. I-Ieretofore, considerable difficulty-has been encountered with this type of construction in that there is a tendency for water and moisture to seep in between the metal sash construction and wooden sill causing dry rot and resulting in a relatively rapid aging and deteri- 1 oration of said wooden sill and wooden back stop, as well as causing warpage of said sill and back stop, which tends to throw the metal sash construction out of alignment.

The primaryobject of the invention resides in the provision of a metal sash and store front construction which will effectively prevent the seepage-of water and moisture between said construction and the wooden sill and back stop with which it is associated, thereby maintaining the said sill and back stop perfectly dry and eliminating dry rot, deterioration, and warpage, as well as reducing to a minimum the necessity of repair or replacement of the said sill and back stop.

Other objects and advantages of the invention will become more apparent during the courseof the following description, when taken in connection with the accompanying drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the same;

Fig. 1 is a front elevation illustrating a store front embodying thepresent invention;

Fig. 2 is a vertical sectional view through one other form of sash construction embodying the invent-ion;

structions being illustrated in Figs. 2 and 5 by way of example.

Referring to that form of the invention illustrated in Figs. 2 and 3, the metal sash construction I2 is mounted on a wooden sill l4 and is secured to a wooden back stop l5 which is carried upon said sill. 'Ihe wooden sill l4 may be faced with Vitrolite or other decorative sheeting It, being held in position'by a mastic ll or other suitable supporting means. a

The sash construction [2 comprises a stationary back section [8 and a movable front section I9 associated with one another to clamp the glass sheet 20 in position therebetwe en. The back section [8 comprises a vertical rear wall 2| which abuts the wooden backstop I5 and is secured thereto by wood screws 22. Formed integral with the rear wall 21 adjacent its upper end is an inwardly directed gutter portion 23 terminating in a substantially vertical lip Mengaging the inner face of the glass sheet 20.

Formed integral with therear wall 21, at the lower end thereof, is a forwardly directed substantially horizontal ledge 25, having at its outer end a vertically thickened portion or web 26 from which extends a horizontal base plate 21. The front end of the base plate 21 is provided with a raised forwardly extending flange 28 which c0- operates with the outer end of said base plate to form a substantially U-shaped channel 2-9 receiving the lower end 30 of the front section IS. The front section [9 comprises a face member 3| provided at its upper end with a lip 32 engaging the outer face of the glass sheet 20, said sheet being supported at its lower edge upon a plurality of setting blocks which, while not shown, are well known in the art. Carried by the face piece 3| are a plurality of spring arms-33 secured at their upper ends in a groove '34 formed in said face piece, while carried at the lower end of each spring arm is a lever member 35 comprising a head 36 from which extends asubstantially horizontal lever arm 31. The head 36' is provided with a series of teeth 38adapted'for selective'engagement with the tooth orrack portions '39 formed on the upper surface of the base plate 21. The tensioning or adjusting means comprises a plurality of set screws 40 threaded through the gutter portion 23 of the back section l8 and adapted to engage the outer ends of the lever arms 37.

To install a light of glass in an opening to be glazed, the back section i8 is first properly secured in place by the screws 22, after which setting blocks are arranged upon the base plate 27 of said back section to support the lower edge of the glass sheet 20. These blocks may be arranged at spaced intervals and should be of a; construction adequate to carry the load of the glass without danger of the glass chipping by reason of contact therewith.

The front section I 9, equipped with the desired number of spring arms 33 and levermembers 35, is then moved into position by placing the end 30 of the face piece 3| under the flange 28 and shoving the same toward the rear section I8 to bring the lip 32 into contact with the outer face of the glass sheet 20, and the inner face of said sheet into contact with the lip 24 of the back section. When properly positioned in this way, the teeth 38 of the lever members 35 will engage a portion of the toothed rack 39 and during this installation, the tensioning screws 40 are all in retracted position so that they will not interfere with proper assembling of the parts. To then secure the glass sheet 20tand front section H9 in position, the tensioning screws 40 are tightened down to the maximum limit possible. This limit will be determined by engagement of the lever arms 31 with the ledge 25, said ledge acting as a positive stop to prevent excessive tensioning of the screws andthereby prevent excessive pressure from being applied to the glass sheet which might result in the breakage thereof. During the tightening of the screws 40, the lever arms 31 will be forced downwardly so that they will rock about the toothed portion 39 on the base plate 21 and as the teeth 38 are in engagement with said toothed portion, movement of the lever arms results in arocking motion which in turn-bends or flexes the spring arms 33. It is this spring tension which clamps the glass sheet 20 between the front andback sections.

When in relaxed position, the spring arms 33 are in a substantially vertical plane, as shown in Fig. 2, so that as the springs are flexed by movement of the levers 31, the pressure exerted upon the glass is in a direct longitudinal or horizontal plane regardless of the thickness of the glass being installed. All of the tensioning screws 40 are operated to bring the levers 31 into contact As brought out above, it is the aim of this with the ledge 25 which eliminates any danger of excessive pressure being exerted upon the glass and the necessity for judgment on the part of the operator.

invention to prevent water and moisture from seeping in between the back section I8 and wooden sill and back stop, whereby to protect the said sill and back stop against deterioration and warpage as well as reduce to a. minimum the necessity for repair and replacement of these parts. To this end, there is provided a metal sill member or cover plate 4| which rests upon the wooden sill l4 and which in turn supports the base plate 2'! of the back section. The sill plate tion of the ornamental facing I6 to give a proper finished effect. The rear end of the sill plate abuts the wooden back stop l and is provided with a forwardly directed wedge portion or element 43 spaced above said sill plate and connected thereto by a web 44, said wedge portion cooperating with the sill plate to form a horizontal groove or channel 45.

, Formed integral with the back section I8 is a rearwardly extending wedge portion or element 45 which is received within the channel 45 for the sill plate. The wedge portion 46 in turn cooperates with the ledge 25 to provide a horizontal =channel or groove 41 within which the wedge portion 43 on said sill plate is received. The channels 45 and 4! face in opposite directions to receive the wedge portions 43 and 46 which are arranged in overlapping, interlocking engagement with one another. Thus, the upper face of the wedge portion 43 is substantially horizontal and this is also true of the lower face of the Wedge portion 46, which is in horizontal alignment with the. base plate 21. The inner meeting faces 49 and 50 of the wedge portions 43 and 46 respectively are, however, correspondingly beveled so as to provide a sliding, wedging action therebetween.

In the installation of the sash construction, the sill plate 4! is first mounted upon'the wooden sill l4, after which the back section I8 is placed upon the sill plate and secured to the back stop, l5 by the screws 22. When this is'done, the back section is forced rearwardlyso that the wedge portion, 43 of the sill member will be received in the channel 41, while the wedge portion 46 is received in the channel 45. As the screws 22 are tightened, the beveled surfaces 49 and 50 of the wedge portions 43 and 46 respectively will slide over one another with a definite. Wedging action and form awater-tight joint which will effectively prevent the passage of water. and moisture therebetween. .The length of the wedge portions 43 and 46 is slightly less than the depth of the channels 45 and 4'! so that when the back section is secured-in place, the outer ends of said wedge portions will terminate slightly inwardly of the bottoms of the channels as shownin l ig. 2. These spacesa-t thebottomsof the channels 45 and 41 act as capillary breaks toprevent the, passage of water or moisture. With this construction, water and moisture is effectively prevented from passing between the wedge portions43 and 46 and findingits way be tween the sill plate and wooden sil1,- ,and likewise. between the back section and wooden back stop.

In order to assist in preventing water and moisture from seeping in beneath the-base plate 21,, the said plate may be provided with one or more longitudinally extending grooves ,5! in which is disposed suitable calkingmaterial 52[ The grooves 5! will also act ascapillary breaks if no calking material is used. I

As shown-inFig. 1, the metal sash construction i2 is adapted to be used around the entire opening [0 to be glazed and in Fig. 4, the sash construction above described is shown as applied to the top of the window opening. l'n th is case; however, thehead plate 53 covering the wooden top or lintel 54 of the window is ofua slightly different construction than the s i ll plate Al in Fig. 2.. Thus, the head; plate 53 extends at its forward end beyond the lintel 54 and is provided with a vertical flange 55 overlapping the mar ginal portion of the ornamental facing 56 and secured in place by-:mastic,51 or, other suitable supporting means. Formed integral with;the

amp?

fiangejfi and spacedabove the bottom: of the 1inte1-5 l isaninwardly directed horizontal ledge .58 for supporting the ornamental facing 56 and terminating in a vertical leg 59 which is secured to said lintel by wood screws 60; With this construction, any water or moisture which may pass downwardly between the flange 55 and ornamental facing 56 will ,be'prevented by the vertical leglifl from coming intocontact with the wooden lintel fa l. If desired, the lower portion of the flange 55 can be spaced from the ornamental facing 5% to provide a recess 6| for catching any end of the ornamental facing it, while provided at the rear end of said sill plate is a forwardly directed wedge portion 64 similar to the wedge portion 53 in 2. {The metal sash construction comprises stationary back section 65 and movable front section 65 provided with lips 6'! and 553 respectively between which the glass sheet 68 is adapted to be secured. The back section 65 is provided with a vertical rear wall 10 which abuts the wooden back stop l5, said rear wall beingprovided at its lower end with a forwardly directed horizontal ledge H and a forwardly directed horizontal base plate i2 connected with saidledge by a webflii.v Also formed integral with ac web it is a forwardly directed flange 14 00- operating with the base portion 12 to provide a channel within which the in-turned flange 15 of the front section 6% is received, said front section comprising a face plate 16 formed at its upper end with said glass engaging lip 68 and at its lower end with said in-turned flange 15. The face plate it is secured in position by screws 11 which pass beneath the glass sheet and through openings in the rear wall 10, being screwed into the back stop l5.

Also formed integral with the web I3 and extending rearwardly is a wedge portion 18 similar to the wedge portion 46 in Fig. 2, said wedge portion I8 being received beneath and cooperating with the wedge portion 64 to form a watertight joint, the inner surfaces of said Wedge portions being correspondingly beveled as at 19. The base plate l2 may also be provided, if desired, with one or more grooves filled with calking material Sill, while the glass sheet 69 can be supported at its lower edge upon a plurality of spaced setting blocks 81.

It is to be understood that the form of the invention herewith shown and described is to be taken as the preferred embodiment of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
